should be considered merelyillustrative "6f ?the principles of the invention -in its broader aspects.

In the drawing:

Fig. 1 is a-side elevation, with certain parts cut away, of a cigar lighter having a casingv constructed in accordance with the preferred form 'of the invention; I v

"Fig. 2 is "a viewpartly in section taken along the line 2-2 of Fig. 1 and looking in the directicn of the arrows;

Fig. 3 is a perspective view showing the constructional detail of one element of the casing structure;

Fig. 5 is a side elevation partly in section of the element shown in Fig. 3.

In the drawing, the preferred form of the invention is illustrated as applied to a lighter of a-wn iknow-n general rcon'struction having aqua acas'ing 'generrtlly indicated at l'llfrom which protrutles i-a wick ttibe fl whi'ch'alsoserves as-a seat for snufier rot'atably mounted on an aile l 3*suppOrted'on' ear-s T3 the-axle also carry- 'irrgfthereon a spai'king wheel I 4. A reciprocable fingerpie'ce fli is" provided and operates uponthe depression thereof tc r-r otatethe sparking wheel P4 "by mechanism wll 'known in the art and 'therfore not-shown-oridescribed in detail) to project spar-kscnto a *W'i'ckcarfied "within "the inte tate ii and simultaneously therewith; "the -snuiferP2 is "caused to siiiingupwardlytoiexpose the wik to "the'pro'jectedsparks. Since'warious. forms *o'f 'the' lighter o'f the general construction and -anode" ofoperationns' thus 'far. described are well knownin "the art "to which "the invention pertains; same will-not be described 'greater iletail herein.

In the form '61 -tlreinvention illustrated, the fuel casing ll) comprises .a side wall structure it which definesiand "surrounds the ful 'chaniber, and "topand bottom end "walls I"! and '18 respectively; each 'ofthe en'dwalls serving to close the fuelphamber. Thetop'andbottomend'walls "are provideiiwith openings "22 and 23 respectively'whichfreeeivethe' pposite ends: of a bent "ii-int tube 24 -extendingthrough the fuel chambexyso thata flint 2'4 maybe inserted into one endfdfthe" flint tube and passe'dthroughthe 'tube to the Uppenend thereof which penetrates the top wan IT by'way of opening ZZYtherin adjacentthetsparkingwheel 1.4. The flint .tiibe ffids 'ffixedlysecured to thebottom end wall 18, ands. screwfi .fitsintothelower end of. the flint Ztiibe fior the'usual purposes. The upper end of the'flinvtube is "threaded i-as at'126 .to receive :a substantially cup shaped nut memberlfl threaded 'along'thel'interiorfthereof .as at'lfl, Fig.5. As the .nut "21 -is "tightened on the "threaded upper end of the ."fiinVtiibe, Tit ioperatesftto'impose .tension on theiiint tube, thereby causing the flint tube :to serve as asreinforcing bolt whichesecurely clamps the separately :noristiuted-end rwallsof -.-the .fuel casing to the side wall structure. After the nut member 21 is tightened on the flint tube, the nut preferably is sealed to the top end wall I! as by soldering indicated at 30, Fig. 1, to provide a fluid tight seal therebetween. The joints of the casing structure, after assembly, may be soldered in the usual manner to provide a fluid tight seal.

It may happen in service that cigar lighters oi the type herein described are overcharged with fuel so that the fuel may spread along the exterior surface of the fuel casing and upon the igtion, and prevent them from loosening up even though the soldered joints are weakened.

It should be noted that the opening 22 provided in the top end wall I 7 adjacent the sparking rounding a fuel chamber, an end wall closing one end of said sidewall structure, a sparking wheel journaled exteriorly of said end wall, said end wall having an opening therethrough adjacent said sparking wheel, another wall of the said casing structure also having an opening therethrough, a flint tube extending through said fuel chamber between said openings, one end portion of said flint tube projecting through said above mentioned end wall opening to a point adjacent said sparking wheel, and a flint tube clamping member surrounding the aforesaid projecting portion of the flint tube, said clampw-ing member having locking engagement with wheel 14 is greater in diameter than the flinttube. The nut 21 is so formed with a spherically curved outer surface, as shown, that upon threaded engagement with the flint tube, it will accurately position the upper end of the flint tube with respect to the opening 22, and also with respect to the sparking wheel i4, thereby insuring that the flint 24' will be positioned in proper tangential relation to the sparking wheel, to project the sparks accurately onto the wick. This accurate positioning of the flint also minimizes jamming of the latter against the sparking wheel when the flint has been worn thin.

For convenience in threading the nut 21 to the upper end of the flint tube, I have formed a pair of oppositely disposed slots, such as 29, Figs. 3 and 5, in the outer periphery thereof, which slots may conveniently be engaged by a tool 31 having detents 32 engageable within the slots 29 of the nut.

While the invention has been disclosed as embodied in a lighter of the above-described specifie construction, it should be understood that changes may be made therein without departing from the invention in its broader aspects, within the scope of the appended claims.

I claim:

1. A cigar lighter casing structure of the character described, having a side wall structure surrounding a fuel chamber, an end wall closing one end of the side wall structure, a sparking wheel journaled exteriorly of said end wall, said end wall having an opening therethrough adjacent said sparking wheel, said end wall being separately constructed from the side wall structure, a second end wall at the opposite end of said side wall structure also having an opening therethrough, a flint tube extending through said fuel chamber between said openings, said opening adjacent said sparking wheel beingilarger in cross section than the flint tube, one end portion of said flint tube being fixedly connected with the second end wall and the opposite end portion of the flint tube being threaded, and a nut member acting between the threaded portion of said flint tube and said end wall having the larger opening, to fix the position of the adjacent end of the flint tube with respect to the sparking Wheel.

A cigar lighter casing structure of the character described, having a side wall structure sursaid projecting portion of the flint tube to hold said clamping member against outward movement along said flint tube, said clamping member also overlying'said end wall to hold said end wall against outward movement along said flint tube.

3. A cigar lighter casing structure of the character described, having a side Wall structure surrounding a fuel chamber, an end wall closing one end of said side wall structure, said side wall and end wall being separately constructed, a sparking wheel journaled exteriorly of said end wall, said end wall having an opening therethrough adjacent said sparking wheel, another wall of the said casing structure also having an opening therethrough, a flint tube extending through said fuel chamber between said openings, one end portion of said flint tube projecting through said above mentioned end wall opening to a, point adjacent said sparking wheel, means for sealing the joint between the side wall structure and said end wall and also the joint between the projecting end portion of' the flint tube and the end wall, and a flint tube clamping member surrounding the aforesaid projecting portion of the flint tube, said clamping member having locking engagement with said projecting portion of the flint tube to hold said clamping member against outward movement along said flint tube, said clamping memberalso overlying said end wall to hold said end wall against outward movement along said flint tube.
